Didier Drogba is featured in a new autobiography called "Commitment" and in it, he reveals why Andre Villas-Boas failed at Chelsea. He believes he had too much faith in his own ability.

Out of the whole Abramovich era so far, it's a toss up between Luis Felipe Scolari and Andre Villas-Boas as to who was the worst appointments during his tenure. Scolari came here with a big, big reputation but it was AVB in my opinion that was the worst because it was such a costly appointment for the club.

AVB came with a reputation of being another Mourinho, tactically astute, a great man manager who could get the best out of his players and someone who studies the game in great detail. After an impressive season, Chelsea paid ridiculous money to lure him from Porto and even bigger money to sack him months later.

Speaking about AVB, Drogba was asked of rumours at the time of AVB wanting to get rid of the likes of Ashley Cole, Frank Lampard and Drogba himself. Drogba responded by saying:

“That’s his right, because the club needed to keep moving forwards, but he shouldn’t have kept those players at the club while he was trying to make his revolution.Although we weren’t going around complaining, it had an impact on the rest of the squad if we weren’t happy.”You have to be able to listen [to experienced individuals] and communicate with them.Otherwise, if you manage a team like Chelsea, you’re heading for a fall.”

That's why we are suffering at the moment this season. We have a real lack of experience as we did back in those days. Back then we had players that could drag us out of a rut, could do something to win you games you looked like losing or dropping points and Drogba was such a massive influence both on and off the pitch.

You only have to look at Tottenham and the fact that AVB lasted just beyond one season there to see that it's obvious that he refuses to adjust to the players he has and sticks to his own personal opinions of how he wants them to play. It's taken a couple of seasons in Russia but Zenit look like a good side now.

Football is about man-managing your players these days as it as about being tactically aware. If you cannot establish a personal link with them you have lost half of the battle.

That's exactly what happened at Chelsea for AVB but I will say this. I am glad it happened because we all know what happened a few months later in Munich!
